I want a talented TE as well...but it doesn't seem like a very strong group. I would probably shoot for an upside play in the middle rounds (3-4).
So much can change if Hunter Henry (or Austin Hooper) becomes available. In that case...Ballard has to make Henry the priority in FA. So fingers crossed.
This is all a real stretch. You cannot count Fountain he didn't make it out of training camp and he may have had the same type of impact as Cain. Ebron is not a WR and you can't blame JBs poor deep throw QB rating on his injury because he has missed one game in these stats.
Same thing with Rogers... he's been there all season and just got hurt a few days ago, his injury is not why JB struggles with the deep pass. Lastly with TY and Campbell, JB has not had great deep passing when they have played but it would be interesting to do a comparison of JB's 20 yard QB rating with TY and without. I would guess it's not that different.
So, in conclusion. JBs poor rating over 20 yards can't be blamed on the loss of the top 6 WRs or pass catchers (if you want to now change the term), because they have not been missing the entire year and there hasn't been a huge drop off after some got injured.
